In some implementations, the clip-on accessory includes an opening centered in a frontal portion of the clip-on accessory. The opening has a height that depends on a height of a sensor of a see-through head-mounted device, to which the clip-on accessory is configured to be attached to, as illustrated in FIGS. 1-3 and 9. In some implementations, the clip-on accessory includes a central bridge with a curved bottom margin, as illustrated in FIGS. 1-3 and 9. In some implementations, the clip-on accessory includes attachment arms with particular curvatures and various lengths to enable attachment to see-through head-mounted devices of various sizes, as illustrated in FIG. 9. In some implementations, sections of the clip-on accessory that are configured to cover eyepieces of the head-mounted devices, to which it attaches, are made of opaque material, semi-transparent material (e.g., to block or enable transmission of a particular wavelength), or substantially transparent material.

The broken lines illustrate environmental features that form no part of the claimed design. 

CLAIM The ornamental design for a clip-on accessory, as shown and described.
